Then, thefirst upper guide member 81, the second upper guide member 91, and thesecond lower guide member 93 are fixed to the inner panel 50 by thebolts inserted into the mounting holes 50 d, 50 f, and 50 g andtightened with nuts screwed on the inserted portions thereof.

Members other than the first lower guide member 83 in this embodimentare pulleys. Also, the first lower guide member is a fixed guide formedwith a groove which allows engagement of the wire 71 on an outerperipheral surface thereof. Furthermore, the first upper guide member 81is supported on the base 61 of the wire drive unit 57 via a bracket 80.

The first lower guide member 83 is mounted on the inner panel 50 using abracket 131. The bracket 131 is formed with a column-shaped projection131 a on the surface opposing the inner panel 50 on the side of one endportion thereof as shown in FIG. 4. The projection 131 a is fitted intoa hole 50 m of the inner panel 50, so that the bracket 131 is rotatableon the surface which is substantially parallel to the inner panel 50.The first lower guide member 83 is fixed to a midsection of the bracket131 by techniques such as welding or screwing.

The first lower guide member 83 is formed with a female screw hole 83 atoward the bracket 131. The bracket 131 is formed with a hole 131 bwhich opposes the female screw hole 83 a of the first lower guide member83. Then, the bracket 131 and the first lower guide member 83 aremounted on the inner panel 50 by a bolt 133 which is penetrated from themounting hole 50 e of the inner panel 50 through the hole 131 b of thebracket 131, and is screwed into the female screw hole 83 a of the firstlower guide member 83.

In addition, the inner panel 50 is provided with five large holes(service holes). Formed at a substantially center portion is a hole 50 hfor installing the window regulator. Formed on an front upper portion isa hole 50 i for assembling a door-inspection apparatus, and formed on afront lower portion is a hole 50 j for assembling a door speaker. Formedon a rear lower portion is a hole 50 k for assembling the windowregulator and formed on a rear upper portion is a hole 50 l forassembling a door lock apparatus.

The wire 71 is wound on the first lower guide member 83, the first upperguide member 81, the second lower guide member 93, and the second upperguide member 91 in sequence in a substantially N-shape.

First window glass mounting means (glass holder) 101 for mounting thewindow glass 53 is provided on a portion of the wire 71 between thefirst upper guide member 81 and the first lower guide member 83 (aportion of the wire 71 extending along the direction of upward anddownward movement of the window glass 53). Also, second window glassmounting means (glass holder) 103 for mounting the window glass 53 isprovided on a portion of the wire 71 between the second upper guidemember 91 and the second lower guide member 93 (a portion of the wire 71extending along the direction of upward and downward movement of thewindow glass 53).

The window regulator 55 is provided with the slack preventing means foreliminating the slack of the wire 71. In this embodiment, first slackpreventing means 111 is provided between the wire drive unit 57 and thesecond upper guide member 91. Also, second slack preventing means 113 isprovided between the wire drive unit 57 and the first lower guide member83. The structure of the first slack preventing means 111 and thestructure of the second slack preventing means 113 are the same.Therefore, the description of the structure is given by the second slackpreventing means 113, and the description of the structure of the firstslack preventing means is omitted.

As shown in FIG. 3( b), a tube 121 for allowing insertion of the wire 71in the interior thereof is arranged between the wire drive unit 57 andthe first lower guide member 83. The side of one end portion of the tube121 is fitted to a bottomed hole 61 a provided on the base 61 of thewire drive unit 57. The side of the other end portion of the tube 121 isfitted to the bottomed hole 84 formed on the first lower guide member83. Arranged in the interior of the bottomed hole 61 a of the wire driveunit 57 is a resilient member (coil spring) 123 configured to urge thetube 121 toward the first lower guide member 83 by being abutted againstthe bottom surface of the bottomed hole 61 a at one end portion andbeing abutted against an end surface of the tube 121 at the other endportion. Then, when the wire 71 between the wire drive unit 57 and thefirst lower guide member 83 is loosened, the resilient member 123expands and the tube 121 is pushed out from the bottomed hole 61 a, sothat the slack of the wire 71 is absorbed. In contrast, when the wire 71between the wire drive unit 57 and the first lower guide member 83 istensed, the resilient member 123 contracts and the tube 121 is furtherinserted into the bottomed hole 61 a, so that the slack of the wire 71is absorbed.

Furthermore, as shown in FIG. 1, a tube 125 for allowing insertion ofthe wire 71 in the interior thereof is also arranged between the firstupper guide member 81 and the second lower guide member 93.

An operation of the configuration described above will now be described.The first slack preventing means 111 and the second slack preventingmeans 113 are configured to absorb the slack of the wire 71 to preventthe wire 71 from coming off the guide member.

When the motor 63 is moved to rotate the drum 65 in the normal directionor the reverse direction to move the wire 71, the window glass 53mounted on the wire 71 via the first window glass mounting means 101 andthe second window glass mounting means 103 is moved upward and downward.

Subsequently, a procedure for assembling the window regulator 55 havingthe configuration as described above will be described.

The window regulator 55 is supplied to an assembly process in a state ofbeing bundled with a band 151 so as to prevent a wire portion fromgetting tangled up as shown in FIG. 5.

(1) The window regulator 55 is inserted into a space between the innerpanel 50 and the outer panel 51 from the hole 50 h at the center portionof the inner panel in a state of being bundled with the band 151 asshown in FIG. 5.

(2) The wire drive unit 57 is mounted on the inner panel 50.

(3) The first upper guide member 81 supported via the bracket 80 ismounted on the inner panel 50.

(4) The bunt 151 is cut off. Then, by the urging forces of the springsof the first slack preventing means 111 and the second slack preventingmeans 113, the wire 71 is moved in the directions indicated by an arrowD and an arrow E in FIG. 1, and the window regulator 55 is deployed in apredetermined shape without tangling of the wire 71.

(5) The second upper guide member 91 is mounted on the inner panel 50using the hole 50 l of the inner panel 50.

(6) The second lower guide member 93 is mounted on the inner panel 50using the hole 50 k of the inner panel 50.

(7) The first lower guide member 83 is mounted on the inner panel 50using the hole 50 j of the inner panel 50. More specifically, theprojection 131 a of the bracket 131 is fitted to the hole 50 m of theinner panel 50. By the urging force of the slack preventing means, thebracket 131 assumes a position indicated by a double-dashed line inFIG. 1. Here, a hand is inserted from the hole 50 j of the inner panel50, an operating force is applied at the other rotating end portion ofthe bracket 131 on the other side, the bracket 131 is rotated againstthe urging force of the slacking means, and the female screw hole 83 aof the first lower guide member 83 and the hole 131 b of the bracket 131are brought to oppose the hole 50 e of the inner panel 50. Then, thebracket 131 and the first lower guide member 83 are mounted on the innerpanel 50 with the bolt 133.

(8) The window glass 53 is inserted from a hole formed on a belt line.Using the hole 50 i of the inner panel 50, the window glass 53 ismounted on the first window glass mounting means 101. Using the hole 50k of the inner panel 50, the window glass 53 is mounted on the secondwindow glass mounting means 103.

In this configuration, the following effects are achieved.

(1) The bracket is 131 mounted rotatably on the inner panel 50.Therefore, the first lower guide member 83 may be guided to the mountingposition on the inner panel 50 only by rotating the bracket 131, so thateasy assembly is achieved.

(2) The one of the end portions of the bracket 131 is mounted rotatablyon the inner panel 50 and the first lower guide member 83 is provided atthe midsection thereof. Therefore, the bracket 131 may be rotated withthe weak force by the principle of a lever only by applying theoperating force to the side of the other end portion of the bracket 131.In other words, the first lower guide member 83 may be guided to themounting position on the inner panel 50 with the weak force, so thateasy assembly is achieved.

(3) By the fact that the rotating plane of the bracket 131 issubstantially parallel to the inner panel 50, the invention is alsoapplicable to a door whose distance between the inner panel 50 and theouter panel 51 is small (a door having a small thickness).

Second Embodiment

Although the rotating plane of the bracket is substantially parallel tothe inner panel in the first embodiment, it may be a directionintersecting the inner panel. In this embodiment, a case in which theguide member to be mounted at last is the second lower guide member 93is assumed. As shown in FIG. 6( a) and FIG. 6( b), the second lowerguide member 93 is provided at a midsection of a bracket 201.Furthermore, a bolt 203 is provided on a surface of the bracket 201opposing the inner panel 50. The bracket 201 is formed with a shoulder201 a on the side of one end portion thereof. In contrast, the innerpanel 50 is formed with a hole 207 which allows engagement with theshoulder 201 a of the bracket 201, and a hole 209 which allows insertionof the bolt 203.

Then, when the shoulder 201 a of the bracket 201 is inserted into thehole 207 of the inner panel, the bracket 201 is brought into a state inwhich the side of the other end portion of the bracket 201 is apart fromthe inner panel 50 as shown in FIG. 6( b) by the urging force of theslack preventing means. Here, the operating force in the directionindicated by the arrow E is applied to the other rotating end portion ofthe bracket 201. Then, the bracket 201 rotates on a plane whichintersects the inner panel 50 about the shoulder 201 a as a fulcrumagainst the urging force of the slacking means. Then, the bolt 203 ofthe second lower guide member 93 is inserted through the hole 209 of theinner panel 50, and the bracket 201 and the second lower guide member 93are mounted on the inner panel 50 using a nut, not shown.

In this configuration, the side of the surface of the inner panel 50opposing the outer panel is needed to have a portion where components orthe like cannot be disposed (a dead space) so as to avoid interferencewith the rotating bracket. However, in this embodiment, the rotatingplane of the bracket 201 is the plane intersecting the inner panel 50,so that the dead space on the side of the surface of the inner panel 50opposing the outer panel 51 may be small.

Third Embodiment

There is a method of using a jig instead of the bracket. In thisembodiment, a case in which the guide member to be mounted at last isthe second lower guide member 93 is assumed. As shown in FIG. 7( a) andFIG. 7( b), a jig 401 is formed with a recess 401 a in which the secondlower guide member 93 is stored at a midsection thereof by techniquessuch as folding technique. A bottom surface 401 b of the recess 401 a isformed with a hole 401 c for allowing loose fit of a revolving shaft ofthe second lower guide member 93. In addition, formed on a side portionof the recess 401 a are substantially L-shaped two claw portions 401 dand 401 e which are engageable and disengageable with the surface of thesecond lower guide member 93 opposing the inner panel 50. In thisembodiment, the jig 401 is manufactured of resin having flexibility.

Therefore, the bottom surface 401 b of the recess 401 a, two wallsurfaces 401 f and 401 g of the recess 401 a, and the two claw portions401 d and 401 e of the jig 401 constitute a guide member mountingportion which allows the engagement and disengagement of the secondlower guide member 93.

In addition, the jig 401 is formed with a shoulder 401 h on the side ofone end portion thereof as in the case of the bracket 201 in the secondembodiment. A bolt 403 is provided on a surface of the second lowerguide member 93 opposing the inner panel 50.

As shown in FIG. 7( c), the inner panel 50 is formed with the hole 207which allows engagement with the shoulder 401 h of the jig 401, and thehole 209 which allows insertion of the bolt 403 of the second lowerguide member 93.

Then, as shown in FIG. 7( c), when the shoulder 401 h of the jig 401 isinserted into the hole 207 of the inner panel 50 in a state in which thesecond lower guide member 93 is placed on the recess 401 a of the jig401 and the claw portions 401 d, 401 e are engaged with the second lowerguide member 93, the jig 401 assumes a state as shown in FIG. 7( c) bythe urging force of the slack preventing means. Here, an operating forcein the direction indicated by an arrow F is applied to the otherrotating end portion of the jig 401. Then, the jig 401 rotates on aplane which intersects the inner panel 50 about the shoulder 401 h as afulcrum against the urging force of the slacking preventing means. Then,the bolt 403 of the second lower guide member 93 is inserted through thehole 209 of the inner panel 50, and the second lower guide member 93 ismounted to the inner panel 50 using a nut, not shown. Then, when the jig401 is rotated in a direction opposite from the arrow F, the clawportions 401 d, 401 e are resiliently deformed, and the engagementbetween the claw portions 401 d, 401 e and the second lower guide member93 is released, so that the jig 401 may be removed.

In this configuration, the following effects are achieved.

(1) The jig 401 is mounted rotatably on the inner panel 50. Therefore,the second lower guide member 93 may be guided to the mounting positionon the inner panel 50 only by rotating the jig 401, so that easyassembly is achieved.

(2) Since the jig 401 is mounted rotatably on the inner panel 50 at theone end portion thereof, and is provided with the second lower guidemember 93 in the midsection thereof, the jig 401 may be rotated with thesmall force by the principle of a lever by applying the operating forceon the side of the other end portion of the jig 401. In other words, thesecond lower guide member 93 may be guided to the mounting position onthe inner panel 50 with the weak force, so that easy assembly isachieved.

(3) The side of the surface of the inner panel 50 opposing the outerpanel is needed to have the portion where the components or the likecannot be disposed (the dead space) so as to avoid interference with therotating jig. However, in this embodiment, the rotating plane of the jig401 is the plane intersecting the inner panel 50, so that the dead spaceon the side of the surface of the inner panel 50 opposing the outerpanel 51 may be small.

(4) The bracket 131 and the bracket 201 in the first and secondembodiments are members which function only in the component mountingoperation, and do not function for the operation of the wind regulatorapparatus. The bracket 131 and the bracket 201 are left in the door.

In contrast, in the third embodiment, the jig 401 is a member whichfunctions only in the component mounting operation, and does notfunction for the operation of the wind regulator apparatus. However, thejig 401 is removed and is not left in the door. Therefore, weightreduction of the wind regulator and cost reduction of the components areachieved.

The present invention is not limited to the above-described threeembodiments. Although the wind regulators in the above-described threeembodiments have been described as a type having the four guide membersand the wire being wound in the substantially N-shape, it is needless tosay that it may be applied to a wind regulator having two guide membersdescribed in the related art.
